SAFETY-RAZOR.

Specification of Letters Patent.

Application filed June 27, 1911.

To all whom it may concern Be it known that I, BENNO VOM EIGEN, acitizen of the United States, residing at Newark, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Safety-Razors;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and v use the same, reference beinghad to the accipal object to provide a novel and simpleconstruction ofsafety-razor, and a means therefor for engaging the separable razorbladenear the cutting edge of the same and positively clamping that portionof the blade, near and along its cutting edge, upon the supportingmember of the blade-retaining casing or element.

The invention has for its further object to provide a simply operatingand hinged blade-clamping means for safety-razors, said means being madein the form of a cover for inclosing most of the razor-blade, except theprojecting cutting or shaving portion of the blade, and serving at thesame time, when the'hinged cover is closed, as a positively actingclamping device for retaining the razor-blade in its clamped andoperative relation upon the supporting member of the blade-retainingcasing, but the said hinged cover being readily forced back into itsopened relation by means of a slight. pressure upon a thumb-latch, withwhich the said cover is provided, and the V spring-like action of theclamping member of the said cover with the shaving-blade and thesupporting member .of the blade-retaining casing.

Other objects of this invention not at this time more particularlyenumerated will be clearly understood from the following detaileddescription of the present invention.v

With the various objects of this invention in view, the said inventionconsists in the novel safety razor hereinafter set forth; and, theinvention consists, furthermore, in the novel arrangements andcombinations of the several parts, as well as in the details of theconstruction of the same, all of which will be more fully described inthe following specification, and then finally embodied in the clauses ofthe claims which are appended to and which form an essential part of thesaid specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a side elevation and Fig. 2 is a rear view of asafety-razor made according to and embodying'the principles of thepresent invention; and Fig. 3 is a top View of the same. Fig. 4 is asimilar view, with the hinged razor-blade retaining cover in its openrelation to the blade-supporting member of the safety-razor, said viewshow ing also in plan, the general arrangement of the razor-blade uponthe said supporting member. Fig. 5 is a transverse section of thesafety-razor, said section being taken on line 55 in said Fig. 3, thehandle of the device, however, being represented in elevation; and Fig.6 is a similar sectional representation of the safety-razor, saidsechandle being also shown in elevation.

Similar characters of reference are employed in all of the abovedescribed views, to indicate corresponding parts.

Referring now to the several figures of the drawings, thereference-character 1 indicates a complete safety razor showing oneembodiment of the features of the present invention, the blade-retainingcasing of which comprises an angularly disposed baseplate 2, forming ablade-supporting member, as will presently appear. This base-plate isusually formed with a downwardly extending and perforated boss or hub,as 3, which is preferably pressed out of the said baseplate andtherefore forms an integral part thereof, the said boss or hub formingwith said base-plate 2, a recess or depression, as 4.

Arranged in this recess or depression is the head 5 of a screw, thescrew-threaded shank 6 of which extends through the perforation in thesaid boss or hub 3 and is screwed into a screw-threaded portion 8 of asuitable handle '7. The preferred method of permanently securing thisscrew to the said boss or hub is by means of a slight annular projection9 which is formed upon the said screw- 'lation with the said base-plate.

threaded shank at the proper distance below the head 5 of the screw, andby means of a suitable tool is upset and firmly pressed against thelower surface of the boss or hub,- so as to provide a shoulder whichsuitably surrounds the hole or perforation in the said boss or hub, andthereby securely joins the said screw to the said base plate againstdisplacement therefrom, as will be clearly evident. Of course it will beunderstood, however, that the said screw may be otherwise secured to thesaid base-plate; or, that any other fastening means may be employed forsecuring the handle of the safety-razor to the said base-plate. Asshown, the said baseplate 2 is formed along one of its marginaledge-portions with a downwardly extending lip or projection, as 10,which acts as a reinforcing or strengthening means, and in which thereis a depression, as 11, which forms a catch-portion or holding meanswith which the thumb-piece or catch of a pivoted or hinged cover to bepresently more fully described is adapted to be sprung into retaining orholding engagement. At its 01)- pos'it e marginal edge-portion, the saidbaseplate 2 is formed with the usual curved and downwardly projectinglugs 12 and intervening spaces 13, above which the shaving or cuttingedge 15 of the razor-blade 13 rests. At its side-edges, the saidbase-plate 2 is made with upwardly projecting lugs or ears 16 and 17,said ears or lugs 16 and 17 being provided with a space 18 between them,substantially as shown, and the upper marginal edge-portions of saidears or lugs being suitably curved, as at 19, and as clearly illustrated in Figs. 1, 5 and 6 of the drawings. The said base-plate 2 isalso provided at or near the edge-portion which is formed with the lugs12 and the intervening spaces 13 with outwardly projecting pivots orpintlelike fingers 20, upon which are pivotally mounted the perforatedpintle-receiving ears or lugs 22 of a suitably curved cover-member orelement 21. This cover-member or element is made along its marginaledge-portion which is located between the said ears or lugs 22 with adownwardly projecting clamping or binding member 23, and at its oppositeedge'portion the said cover-member or element is made with a downwardlyprojecting marginal rib, as 2 1, which is adapted to rest upon the uppersurface of the said base-plate 2, when the said cover-member or elementhas been brought into its closed re- Connected with and extendingdownwardly from the said marginal rib 241 is a suit-ably curved andslightly outwardly extending thumb piece or catch, as 25, the convexlycurved surface-portion of which can be sprung into separable retainingor holding engagement with the metal forming the depression 11 in thepreviously mentioned lip or projection 10, as will be clearly understoodfrom an inspection more particularly of Figs. 1 and 5 of the drawings.To secure the razor-blade l-l in its operative position upon the uppersurface of the said base-plate 2, the covermember or element 21 isbrought into the raised position indicated in Fig. 6 of the drawings,and the razor-blade which is provided with the laterally extendingmarginal projections 26 arranged upon the upper surface of the saidbase-plate with its cut ting or shaving edge in position above the lugs12 and spaces 13, and the said marginal projections 26 in the spaces 18between the upwardly projecting lugs or cars 16 and 17 of the base-plate2. hen thus arranged, the clamping or binding member 23 of theCOVGF-ll'lBlllbGI or element 21 is in the position indicated in Fig. 6of the drawings, out of engagement with the said razor-blade, so thatthe latter can be readily placed in its position upon the saidbase-plate, or removed therefrom, as the case may be. hen the saidshaving-blade has, in this manner, been placed upon the said base-plateof the blade-retaining casing, with the cutting or shaving edge of theblade extending beneath the clamping or binding member 23' of the saidcurved cover-member or element 21, substantially as shown in Fig. 6 ofthe drawings, and with the said edge of the blade resting partially uponthe lugs 12 of the base-plate, as shown more particularly in F 3 of thedrawings, the cover-member or element 21 is closed down, so as to bringits thumb-piece or catch 25 into its holding engagei'nent with thedepressed portion 11 of the lip or projection 10, whereby the mar ginalclamping or binding edge of the said menib'er or element 23' is broughtinto positive frictional engagement with the bladesurfa'ce, slightlyback of the cutting or shaving edge of the blade, in the manner clearlyillustrated in Fig. 5 of the drawings, and whereby, owing to thespring-like action of the metal of which the blade is made, the cuttingor shaving portion of the blade is securely held, along its entirelength, down upon the said lugs 12, so that the device can be mostefficiently used for properly shaving the face. In order that the saidcoverelement or member 21 may be retained in its raised position,represented in said Fig. 6 of the drawings, while removing or replacingthe razor-blade, the pivot-lugs or ears 22 of the cover-member orelement 21 are made with slight projections or fingers, as 27, eachproject-ion or finger 27 being formed with a straight edge or shoulder,as 28 see Figs. 1 and 5, which is adapted to be brought against thelower face of the base-plate 2', and whereby each project-ion. or finger2'? acts as a stop to arrest the opening movement of the saidcover-member or element 21, and thereby hold it in the raised positionshown in the said Fig. 6 of the drawings. IVhen the said cover-member orelement has been closed, the lower edge of the marginal rib 24 restsupon the upper surface of the base-plate 2, and the lower marginalsurface-portions of the covermember or element rest upon the uppermarginal and curved edges 19 of the ears or lugs 16 and 17, with thespaces between the ears or lugs 16 and the pintle-receiving ears or lugs22 closed by the angular parts 28 of the covermember or element 21, sothat a simple, neat and compact razor-blade retaining casing forsafety-razors is provided, which can be readily cleansed after use, andin which there are no parts to get out of order, the movable parts ofthe retaining case being most easily manipulated, by holding thesafety-razor by means of its handle in the one hand, and by means of thethumb of the same hand applying a slight pressure upon the thumb-piece,whereby the latter is released from its holding engagement with thebase-plate, and the cover-member or element automatically springs intoits raised position. I am aware that some changes may be made in thevarious arrangements and combinations of the several parts of thedevice,

as well as in the details of the construction of the same, withoutdeparting from the scope of the present invention as set forth in theforegoing specification, and as defined in the claims which are appendedto the said specification. Hence, I do not limit my present invention tothe exact arrangements and combinations of the several parts asdescribed in the said specification, nor do I confine myself to theexact details of the construction of the said parts, as illustrated inthe accompanying drawings.

I claim 1. In a safety-razor, a razor-blade retaining casing comprisinga base-plate, pintles extending laterally from said base-plate, acover-member, perforated pivot-ears connected with said cover-member,said ears being pivotally mounted upon said pintles, means connectedwith said cover-member for clamping a razor-blade near its cutting edgeupon said base-plate, and a hookshaped projection connected with eachpivot-ear adapted to be brought into engagement with the base-plate andserving as a stop to limit the pivotal movement of the cover-member,said base-plate being provided with a lip formed with a depression, anda thumb-latch connected with said cover-member, said thumb-latch beingadapted to enter said depression and being adapted to be sprung intoretaining engagement with the depressed portion of said lip,substantially as and for the purposes set forth.

2. In a safety-razor, a 121Z0l-blad8 retaining casing comprising abase-plate, pintles extending laterally from said base-plate, acovermember, perforated pivot-ears connected with said cover-member,said ears being pivotally mounted upon said pintles, a downwardlyextending marginal clamping element connected with the said cover-membernear its hinged connection with the said base-plate for clamping arazor-blade near its cutting edge upon said base-plate, and ahook-shaped projection connected with each pivot-ear adapted to bebrought into engagement with the base-plate and serving as a stop tolimit the pivotal movement of the covermember, said base-plate beingprovided with a lip formed with a depression, and a thumb-latchconnected with said covermember, said thumb-latch being adapt ed toenter said depression and being adapted to be sprung into retainingengagement with the depressed portion of said lip, substantially as andfor the purposes set forth.
